What is the little ,blue modern vehicle with traks in one of the shots behind the Snow Trac and the red rig? I have a spare set of Mattrack M3s looking for a project.

Snowtrack restauration project
- Thread starter louis
- Start date
Report of performance at the Hosanna Jamboree
Cold temperature - 30 celcius
Excellent Snow condition, average snow accumulation of 3 feet
Trails were well groomed but a bit too narrow for the snowtrac
First day Friday: 160 km
Second day Saturday: 220 km
Third day Sunday: 60 km
Average consumption for the 3 days trip in cold weather : 17 miles per gallon
In comparaison, a snowmobile C18 on the same Friday trip of 160 km cost him $65 to refill its tank;
To refill my snowtrac tank, it cost me only $25
All Bombardier snowmobile owners were surprised with the low consumption of the Ecotec Snowtrac
At the Hosanna Jamboree, all snowmobiles were Bombardier:
B12 narrow-gauge mostly with original Chrysler T 120 engine
C18/R18 wider gauge with V8 engine “those snowmobiles can go easily 60 to 70 M.P.H. “
Out of the 28 Bombardier snowmobiles at the Jamboree, I would say that 50% now ride on custom made slides (see BANDIT picture bellow )
(they removed the 3 front wheels and install a set of custom slides keeping only the 4 th wheels)
At one place (Lac Canard) in up hill situation all the Bombardier snowmobiles with slides go up easily;
Some of the B12 on wheels need to be winched by the big Bombardier C18; (the slides are definitively superior of the wheels set up)
When the Snowtrac took the challenge, the Ecotec engine make all the differences and successfully climb the hill
*Definitively not the type of expedition for a Snowtrac equipped with a VW engine
The cruise speed in the trail was around 30 mph; to follow the other vehicles, the Snowtrac in 4th gear must rev between 3500-4000 RPM
In the trail, in 4th gear, I went very low speed in turn at 1500 RPM and accelerated to 5000/60000 RPM in straight parts of the trail ; I went back to 1500 RPM at the bottom of a hill to 6500 RPM when I reached the top
I would say I was very surprised with the performance of the Ecotec in those situations
The 175 HP and the torque of Ecotec 2.4 engine are a perfect match with the final gear ratio (16 tooth gear I made)
The heat exchanger and the radiator set up are just fine; the 2 cooling fans did run only a few time
The cabin heater is a good improvement; believe me!
The 12 volt 130 AMP alternator was a good improvement specially for night running (lots of lights)
At the Jamboree, the Ecotec snowtrack was the attraction: no Bombardier snowmobile owners had ever seen one; lots of questions and pictures taken !
To conclude, a snowtrac with an Ecotec 2.4 is the way to go; it is very quiet and vibration free; it performs very well in my custom installation

It would be cool to see more of that Smart. Pretty neat idea / conversion.

... they dont throw roostertails like that
I think this youtube video around the 3 min. mark is a good example. factory literature lists 14-18 MPH top speeds.
https://www.youtube.com/watch?v=OWWAfKvJ8Bc
kind of disapointing after watching Louis' "fly by".
I have to think those axle tubes are going to need upgrading!
FOR JASK
After the big 3 days run at club HOSANNA i check everything ;
Axle tubes ,transmission , chains , chains sprokets ,pulleys, transmission and front engine mount .
No oil leaks , no cracks , all components were fine
The program ecotec did work over my expectation !!!!!!!!!!!!!!!!!!
" FLY BY " 4 th GEAR 6200 RPM

Louis ..
Your father would be very proud with your ST4 and of course we are very interesting about your progress with the ecotec program.
I am Thinking.....
If we had the opportunity to see the movement of the tracks on the snow (In Slow motion with a camera) when the snow trac is running - flying, with that speed.......................

First picture:
Snowtrac and snowshack on the shore of the Saint-Laurent river
Second picture:
Snowtrac and snowshack by night (very cold outside but comfortable inside for the night )
Third picture:
Low tide (the air strip is gone and it is the end of the snowtrac fun)
Fourth and fifth picture:
High tide (In french, we say "C'EST FINI, C'EST FINI !!"
The snowtrac Ecotec performs so well; it is amazing! i have so much power available at any RPM range; during the air strip preparation I was at third gear all the time, changing the speed from 900 RPM to 6500 RPM
Working hard with the snow drag to prepare the air strip for the landing of the airplanes (the outside temperature was minus 9 F, the oil and water temp of the Ecotec were in the green range all the time)
I am very pleased with the snowtrac Ecotec program; I recommend it to have fun or to work with the snowtrac
And to finish, it has a very good gazoline economy compare to the VW engine!

Salut Louis !
Toute q'une Machine.
C'est très impressionnant de voir tes réalisations.
I hope to have time one day to improve my Snow Trac.
So far it does the job to bring me to my back country retreat...
Keep on the good work,
Micrometerstar (Leonard)

its amazing how rough the landings are on skies compared to wheels I miss flying around with my dad when I was young.
I received several private messages concerning the Ecotec conversion.
For the benefit of the Snow Track community, i will answer on my thread
Concerning the snow master of "NWERRING", being rebuilt with a Ecotec 2.4 from a 2011 chevy Malibu.
Question 1: Solo-Performance header?
In my Ecotec installation I used a header expecting to gain 10 HP
During my test program, the Ecotec 2.4 gave me so much horse power so i realized the header is not an absolute must; a regular cast iron manifold from a Pontiac Solstice/Saturn Sky can do the job at a better cost ( see picture )
Question 2: Engine injected or Natural Aspirated?
The Ecotec 2.4 LE5 engine is a OEM reliable fuel injection system
Question 3: Where did you mount the cooling radiator?
I have installed a RADIATOR CAPSULE in the back of the snowtrack (left side) to have a better weight distribution (radiator, fan and prestone 40 pound )
Question 4: "You said you have a set of 15 tooth gear sprockets"
Personnally, i would try the 15 tooth gear setup at the beginning and if you have to make special gear i would go higher up to 17 tooth
For the benefit of all members willing to install an Ecotec engine, i will be happy to answer any questions on my Forums forums thread (Snowtrack restauration project ); so the information will be centralized at the same location
Please post a picture of your SnowMaster with the Ecotec
What are you planning to do for your stand alone computer (GM E67) ?

Thank´s for the answers Louis.
I could not find an engine in Scandinavia, so I got one on eBay in the US. It´s on a ship towards Norway now I also managed to get an exhaust header from a Saturn Sky. I plan to get GM E67 and harness from Alpha Fab Industries. It cost half an arm, but all the wires scare me a little, so better to get a complete kit.
Also, I will try with my 15 tooth gear sprocket.
Now I have to find a solution for the electronic throttle pedal.
I´ll post photos when I get started.

I tried to send you a private message Mike, but your box was full...
Hi Mike,
I might have to take you up on the offer to make custom sprockets. The SnowTrac I use now have a healthy 1600cc single port engine and 15 tooth sprockets. Works fine, but I hardly ever use 1st. gear.
With the Ecotec engine, I think maybe 17 tooth like Louis mentioned, would work fine.
Could you make a set with 17 tooth that fit the metric (?) SnowTrac chainlink?
Regards,
Niels

NWERRING ; FOR THE GEAR built one from the 12th tooth you already have like i did; it cost me less than 25.00 CDN$ each for material only.
FOR 17th tooth gear in the TRACMASTER be careful witch clearance between
the chain and the lower cross member ( square tubing ) see picture
The fromt drive gear in the TRACMASTER is bigger!!!!!!!!!
After 2 winter fun
the SNOWTRAC with my gear set up; no interference witch the cross member
